STMICROELECTRONICS L6563STR Transition-Mode PFC Controller
The L6563S is a high-performance transition-mode PFC controller designed for power factor correction in switching power supplies. It features a highly linear multiplier, optimized crossover distortion correction, and a proprietary voltage feedforward technique that significantly improves line transient response and reduces total harmonic distortion (THD). The device supports tracking boost operation, remote ON/OFF control, and provides enhanced protections including overvoltage, feedback loop failure, brownout, and boost inductor saturation. Its advanced features ensure efficient, reliable operation in high-power applications up to 400 W, compliant with standards such as EN61000-3-2 and JEITA-MITI.
